The MTT MS3702B is a slim plug-in RTD temperature transmitter tuned for narrow-span measurement, where a temperature process moves within a tight band and needs to be resolved with more precision than a wide-range transmitter can offer. It reads a Pt or JPt RTD, linearizes the signal, and delivers it as one or two isolated DC outputs, keeping full accuracy even when the measured span is as narrow as 30-50°C.
Like the rest of the plug-in transmitter range, it clips into its own socket base so the unit can be swapped for calibration or replacement in seconds without disturbing the field wiring. Where a dual-output configuration is used, both outputs remain isolated from each other, the input, and the power supply, so one narrow-span RTD reading can feed a control loop and a monitoring or logging system at the same time. Flexible AC or DC power and wall or DIN rail mounting make it straightforward to fit into an existing panel, and standard upscale burnout protection helps flag a broken sensor rather than reporting a misleading reading.
